We normally see these as tall, indoor-forced winter plants. However, when grown outdoors in the summer with more intense light and longer daylight hours, they bloom on much shorter stems in early-mid summer. 12″-20″ in full sun, taller in part shade; whz 7-10; also in whz 6 in sheltered locations, when planted deep and mulched well; 22/24cm bulbs unless otherwise noted.
